CVE-2026-48381: Adobe Campaign Classic SQL Injection Flaw

CVE-2026-48381 Overview

CVE-2026-48381 is a SQL injection vulnerability affecting Adobe Campaign Classic (ACC). The flaw stems from improper neutralization of special elements in SQL commands [CWE-89]. A remote attacker can exploit this issue over the network without authentication or user interaction. Successful exploitation results in arbitrary code execution in the context of the current user. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component. Adobe published a security advisory (APSB26-123) to address the issue.

Critical Impact
Attackers can execute arbitrary code on affected Adobe Campaign Classic deployments through unauthenticated SQL injection, with impact spanning beyond the vulnerable component due to a scope change.

Affected Products

Adobe Campaign Classic (ACC)
Refer to Adobe Security Advisory APSB26-123 for specific affected versions
Deployments exposing ACC endpoints to untrusted networks

Technical Details for CVE-2026-48381

Vulnerability Analysis

CVE-2026-48381 is classified under [CWE-89], Improper Neutralization of Special Elements used in an SQL Command. Adobe Campaign Classic accepts input that is passed into SQL statements without adequate sanitization or parameterization. An attacker can craft SQL fragments that modify query semantics and reach beyond intended data access boundaries. Adobe's advisory indicates the outcome is arbitrary code execution in the context of the current user. The scope change in the CVSS assessment reflects that impact extends into a security authority beyond the initially vulnerable component, such as the underlying database or host process.

Exploitation is described as depending on conditions beyond the attacker's control, which explains the high attack complexity rating. No user interaction is required, and the vector is network-based.

Root Cause

The root cause is an input handling defect where user-controlled data flows into SQL query construction without proper escaping or use of prepared statements. When a database query executes attacker-supplied SQL, the attacker gains the ability to read, modify, or issue database engine features that lead to code execution in the current user's context. See Adobe Security Advisory APSB26-123 for vendor-specific technical detail.

Attack Vector

The attack vector is remote and unauthenticated. An attacker sends crafted requests to an ACC endpoint that internally constructs a SQL statement from the untrusted input. Because the scope is changed, downstream components such as the database engine or operating system context can be leveraged for arbitrary code execution. Verified proof-of-concept code is not publicly available at the time of writing.

No verified exploitation code has been published. Refer to Adobe's advisory for technical remediation context rather than synthetic examples.

Detection Methods for CVE-2026-48381

Indicators of Compromise

Unexpected SQL syntax fragments (for example, UNION, --, ;, xp_cmdshell) in Adobe Campaign Classic HTTP request logs
Anomalous database queries originating from the ACC application account outside of normal marketing workflows
New processes spawned by the ACC service account, particularly shell interpreters or scripting engines
Outbound network connections initiated from the ACC host to previously unseen destinations

Detection Strategies

Inspect web server and application logs for URL parameters and POST bodies containing SQL metacharacters targeting ACC endpoints
Monitor database audit logs for queries that deviate from application-generated query templates
Correlate ACC request patterns with child process creation events on the host running the campaign server
Alert on stored procedure invocations or file system access from the ACC database session

Monitoring Recommendations

Enable verbose logging on ACC front-end and application tiers, and forward events to a centralized SIEM or data lake
Baseline normal query volumes and shapes for the ACC service account, then alert on statistical deviation
Track child-process creation, script execution, and outbound network activity from the ACC application host

How to Mitigate CVE-2026-48381

Immediate Actions Required

Apply the security update referenced in Adobe Security Advisory APSB26-123 as soon as testing permits
Restrict network access to Adobe Campaign Classic administrative and API endpoints to trusted management networks
Review ACC and database logs for indicators of prior exploitation attempts
Rotate credentials and secrets used by the ACC service account if compromise is suspected

Patch Information

Adobe released a security patch for Adobe Campaign Classic addressing this SQL injection vulnerability. Refer to Adobe Security Advisory APSB26-123 for the fixed versions, download locations, and upgrade guidance specific to your deployment model.

Workarounds

Place a web application firewall (WAF) in front of ACC with signatures that block SQL injection payloads targeting known parameters
Enforce least privilege on the ACC database account, removing rights to execute operating system commands or access unrelated schemas
Disable or restrict any ACC modules that are not required in your environment to reduce attack surface

bash

# Example WAF rule concept (adapt to your platform)
# Block requests to ACC endpoints containing common SQLi tokens
SecRule REQUEST_URI "@beginsWith /nl/jsp" \
  "chain,phase:2,deny,status:403,id:1004826,\
   msg:'Possible SQL injection targeting Adobe Campaign Classic (CVE-2026-48381)'"
  SecRule ARGS "@rx (?i)(union(\s|/\*.*\*/)+select|;\s*(drop|exec|xp_)|--\s|/\*!)" "t:none"
